Note: The graph illustrates that in February, TWA stock went up
$5, to a new price of $45 per share.
Price changes occur once each month, allowing you twelve
opportunities to manipulate your investments.
If a stock rises in price to exceed $100 per share, a stock split
is declared. You get two shares for each of the shares you originally
owned. The price is then divided by two. However, each share
retains its dividend potential. Consequently, when a stock split
takes place, you will gain twice the number of dividends.
If a stock drops below $1 per share, it is declared bankrupt,
and you lose all your holdings in that stock.
You can only buy and sell blocks of stock. Each block; consists
of ten shares.
Dividends are computed for each investor automatically and are
then added to his/her cash.
Each investor's stock prices are evaluated using the newest
prices, and are added to each investor's cash to reveal the total
worth of that individual.
If you wish to buy or sell a block of stock, the following exam-
ples will illustrate the form of buy or sell order to be typed:

Note: A special feature of this program is the computer over-

sell more stock than you own), the computer calculates the amount

Speculation allows you to find out if you would be able to make
money on the stock market.
This is not a game in the conventional sense of the word, since it
Is a very realistic simulation. The investor starts with any amount
up to $10,000 in his/her stock purchasing account; a matching
amount is automatically set up as a savings account at 6.5% interest
rate. (This interest rate can be altered.)
The investor refers to newspaper stock prices, to buy and sell
shares, and all records can be stored on data tape.
The game can be played for a period of up to five consecutive
years (simulated by computer), during which time the savings
account will continue to add and compound quarterly interest.
The game will automatically give net costs, using real commission
rates obtained from Merrill- Lynch in October 1978.
Short of actually investing real cash, this is the closest you can
come to actually playing the stock market.
(1) You start with $10,000 or less, in your stock purchasing
account. An equal amount is automatically deposited in your
sayings account at 6.5% interest rate.
(2) Vou can alter the beginning amount and the savings account
interest percentage rate. However, the alterations can only be
inserted during the first day of a period of speculation. If you
wish to insert further changes, you must wait until the next
game to insert them,
(3) One game of speculation can be extended to cover a period
from a few months all the way to five years.
14) Commissions are automatically computed, then added into
cost and profit predictions when you are analyzing a new
(5) After each 91 days of speculation, the interest is added to your
savings account, compounding that interest on a quarterly
(6) You may add dividends, paid by various companies, at the
beginning of each quarter on the following dates:
January 1st [Caution: Be sure to add dividends quarterly
April 1st [but only once per quarter] , as this dividend
July 1st money adds to your spendable money.)
Note: You simply enter the full amount of these dividends. The
program will automatically divide the dividend by four (4), then
deposit the correct amount to your bank account. (It simultan-
eously deducts the correct amount from the total invested in each
(7) For a stock to qualify for a dividend, you must have owned
it before the change of the current quarter,
(8) You will only be able to own up to 25 different stocks at one
(9) There are no provisions for selling short in this program, be-
cause most novice investors are not in the financial position to
cover possible losses.
(10) During the process of evaluating a stock you will be asked to
supply information relating to that stock. Newspapers list
information on both the New York and American Stock Ex-
changes, including the following items:
(a) The name of the stock
(b) The high and low for the year.
(c) Dividends paid
(d) P/E Ratio (Price-to-Earnings Ratio)
(e) The high and low rates for the week
(1) The closing price for the week
(g) The net change of rate for the week
(11) If you can't get information about the earnings of a particu-
lar company, use the P/E ratio, (Sometimes the projected
earnings are putalished.l These facts are listed in the news-
papers when the company announces its earnings for a year or

stock, although conversely, many times a stock does quite
well with ratios of 20-to-1 and even 30-to-1 .

Often when you have trouble loading a program, it's not rhe fauH of (he tape or
your computer system, ft may be a problem with your cassette recorder. The staff
at Instant Software use a large vartety of cassette recorders eight hours a day, five
days a week. To insure that the recorders will keep up wilh the demands of our work
load, they are subjected to a rigorous maintenance routine.
As ynu run a tape in any recorder, a particle of oxide may flake off the tape, or a
bit of dust may settle from the air, These bits of debris may arthers to the

To keep youT recorder in top condition, clean the recorder heads regularly after
every 15-20 loads or saves. Use denatured alcohol (available at any drugstore) and
cotton tipped swabs. Lightly dampen a swab and gently stroke the erase head, the
record/ptay head, and the pinch roller. This will remove accumulated tape oxide
and dust, You can also use a soft brush or vacuum cleaner to remove dust from ihe

is one of the reasons why a program recorded when you first got your sytem will
not toad several months latei or won't load on another system.
The cure is to have your recorder aligned by a qualified technician, or if you have
the know-how. to align it yourself.
The technicians at histant Software recommend using an industrial standard
alignment tape (they use a Panasonic tape, part No. OZZCFM}. This tape allows
them to test for playback frequency response, playback level, and ihe head azimuth
adjustment. The most critical aspect, especially for PETs, is the azimuth adjustment..
To run a lest on your recorder, connect an oscilloscope to the earphone jack, in-
sert the alignment tape into the recorder, push the play button, and adjust the head
tor the best waveform on the oscillosocope. If you lack tesi ins i rum en ts. adjust the
head for the loudest sound and the best high frequency response without changing
the recorder's volume setting.
Remember, your recorder is a critical link in your computer system. For the best
performance, give it the best care
